The ADAM-6541 is an industrial grade converter which is designed to convert Ethernet network (10/100Base-TX) to fibre network (100Base-FX) by transparently converting Ethernet signals into optical signals. The advantages of fibre-optics are high bandwidth, EMI immunity and the capability for longer transmission distances. This makes the ADAM-6541 an ideal solution for 'fibre to building' applications at central offices or local sites. The converter supports MDI/MDIX auto-detection, mitigating the need for crossover cables. It also includes a switch controller that can sense the transmission speed (10/100 Mbps) automatically.
Both the Ethernet port and the fibre port have memory buffers that support store-and-forward mechanisms, assuring that data is transmitted without errors. The ADAM-6541 is compact and can be mounted in three different ways: DIN-rail, wall and stack. It operates in temperatures from 0 to 60°C and accepts a wide voltage range from 10 to 30 V d.c. It also provides 3000 V d.c. surge (EFT) protection against over-voltage, making it suitable for harsh operating environments.
Aside from its standard features, the versatile ADAM-6541P/6541S also has the LFP (link fault pass-through) feature. When one side of the link fails, the other side continues transmitting packets, and waiting for a response that never arrives from the disconnected side. By enabling the LFP function, the converter will force the link to shut down as soon as it notices that the other link has failed, giving the application software a chance to react to the situation.
